Stacking sewage treatment equipment

Abstract

The invention discloses stacking sewage treatment equipment. The stacking sewage treatment equipment comprises a lower cavity and an upper cavity arranged above the lower cavity; the lower cavity is internally provided with a first-stage settling chamber connected with a blowdown pipeline, a grid is arranged at the joint of the first-stage settling chamber and the blowdown pipeline, the first-stage settling chamber is shaped like a funnel, a collecting bucket is arranged at the bottom of the first-stage settling chamber, and multiple vibration mechanisms are arranged outside the first settling chamber; the upper cavity comprises an anaerobic treatment chamber connected with a lifting pump and an aerobic treatment chamber and a second-stage settling tank which are connected with the anaerobic treatment chamber in sequence through a delivery pipeline. Sewage passes through the first-stage settling chamber, the anaerobic treatment chamber, the aerobic treatment chamber and the second-stage settling tank to be subjected to purification treatment and then discharged outside. Compared with the prior art, the stacking sewage treatment equipment is compact in structure, convenient to install, small in occupied area and suitable for being used by cities lacking land resource and not only effectively improves the sewage purification effect but also saves the land resource.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a stacked sewage treatment equipment. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. The existing sewage treatment equipment occupies a large area, the land cost is high, and the treatment cost is unbearable, etc., making some urban sewage treatment plants become "concentrated pollution discharge sources", causing secondary pollution to the local environmental conditions. With the development of the times and science and technology, people's living standards are improving day...

AI Technical Summary

Problems solved by technology

In sewage treatment projects, inorganic particles in sewage will not only wear equipment and pipelines, reduce the activity of activated sludge, but also accumulate at the bottom of the reaction tank to reduce the effective volume of the reactor, and even break the filter belt during dehydration and damage the dehydration equipment. , and the effect of sewage treatment is not very good. In addition, with the development of industry, land resources have restricted the development of cities, and sewage treatment equipment often needs to occupy a relatively large area, which is a waste of land resources
